Eddie is right, my buddy has 630 on his 13B ported engine and it runs like a dog. put a smaller carb on it and it fuckin flys..

Rotary engines like effiency of flow, not mass of flow, once you learn this the power will come easier..

 

I have a question.

Do you have a EGT or a A/F guage?

 

No, not yet. I NEED one baaaaaad! If I had the cash I would have all the gauges and a RB 465, but I would be pissed if it didnt run 100% better than what I have! I used to have a street port 13b with a stock carb, jetted out and it ran like a Wild Screaming Banshee! My shit currently doesnt run extremely bad, just not up to my standards. I will, in a few weeks start running it at the track and have some starting point.

 

Keep in mind its almost impossible to tune a carb without a set of guages. Don't waste your money on A/F, its just a light show, and really gives no data on how rich or how lean.. EGT is the way to go...I can get them dirt cheap.. I think $75, and $35 for the sensor.

 

Yeah, I really need guages! More than just a/f and egt, but right now I have to put some money into my bike(cr125), it has been down for way too long! ! ! What kind of ride do you have? you avatar says fc but the pic looks more like an impreza?

 

Sorry about not replying..I have many cars.. The car in the picture is my MP3, running Jspec..

 

The latest mods I have done, to my Holley is plugged the power valve and jetted the primaries to 65 and secs to 73 running alot smoother but need to get 68 primary jets. I read a post on mazspeed.com who says to plug the power valve and run 68 prim's and 72 sec's and that is for the 600 on stock port/street port 12a's and 13b's. This current set up is running the best so far for me, but havent had any track time. maybe tomorrow if Iam lucky?
